Minor note about the RTC battery

[tllim]

I just completed my backerkit survey.  On the picture for the battery for the RTC (real time clock), both the CR and the AAA battery packs just have red/black wires.  I would hope the actual battery pack shipped has the appropriate JST-PH plug to go into the pine64 board (or whatever plug you use on the board).

The problem is even a small Lithium coin or Alkaline AAA battery, the paper work to file for custom declaration is a lot of job especially deal with different country.

I realize why you aren't shipping a battery.  That's fine, those are easily sourced.

I meant that the picture on your backer kit will NOT simply attach to your board.  Your board has a white 2 pin connector for the battery to plug into, but your picture shows the battery connection as just two wires.  You really need to have the appropriate plug attached to those wires so that people can attach it to the board without needing to buy a plug and attach it manually.  Or you need to change your board to have a screw terminal to connect the two bare wires.  I assume the picture is more a generic stock picture, but just in case it was the actual board you were going to ship, I wanted to point out, it would be useless to many folk without additional work.

And in general, if the pine64 is expected to be attached to the internet, you don't need the battery for the RTC as you can just NTP to keep the clock synced.  But if you are going to make the board be mobile where you power it on/off and run unconnected to the internet for periods of time, you do need to keep the clock backed up.

It is great that you have the RTC, as one of the minor problems I have with the Raspberry Pi is it didn't have a RTC.  I have add-on boards for doing the RTC, but it is one more thing you have to attach.  In addition, the original board had a design flaw with the i2c bus where it would disappear when I attached the camera.  The newer boards no longer have the problem, but I have one board from the original batch (as well as a newer board).

Thanks on pointing out the photo mistake. The RTC is no need for general purpose application that always connected to Internet, it is only use for certain application that RTC is needed like remote outdoor information collection that needs time stamp. Thanks on your explanation.
